The pantograph is made of aluminum (P-Al MgSi UNI 3569) and manufactured according to DIN 15560-46. The attachments at both ends of the pantograph are 16mm, male on the bottom and female on the top. The load is supported by a steel cable of 2mm. diameter (safety factor 12). Loads up to 26lbs (12kg) can be suspended using only the patented friction device, while loads up to a maximum of 39lbs (18kg) require the use of the optional springs. The pantograph can be regulated to keep suspended loads from 1 to 39lbs perfectly balanced.
